How Common are Pregnancies After Vasectomy Reversal?

pregnancies after vasectomy reversalYou might think that once you’ve gone under the knife and had a vasectomy, that’s the end of the road, but more and more men are changing their minds and opting for a vasectomy reversal in order to try and conceive – with excellent success rates. Pregnancies after vasectomy reversal certainly happen, often within a few months of the surgery too.

The procedure

A vasectomy reversal with Mr Harriss is performed through a single scrotal incision under general anaesthetic, after which he finds the ends of the vas deferens, a small tube in the male reproductive organ that carries sperm. He joins the ends severed in a vasectomy using the single layer technique, and rejoins both sides, allowing the patient the greatest chance of conceiving after the operation.

Sperm motility

Sperm motility is the ability of sperm to propel themselves and move properly through the female reproductive tract and it too can affect fertility. the best indicator of a successful pregnancy would be getting pregnant. Two scientists, Silber and Grotjan, documented results from patients taken across nearly 30 years and concluded that pregnancies after vasectomy reversal are similar to those achieved in the general population for couples with similar age profiles.

Scientific analysis also shows that the pregnancies after vasectomy reversal after a vasoepididymostomy are slightly lower than those achieved with vasovasostomy but none the less, pregnancy rates are generally recognised as being in alignment with the general population.

Reversing a vasectomy is far from a guarantee that pregnancy will follow, and anti-sperm antibodies that are counter-productive to conception can often be found in men who have undergone a vasectomy. They don’t rule out the possibility of a pregnancy, but anti-sperm antibodies can affect conception. However, we have had pregnancies where men had 100% anti-bodies found at their semen analysis so our opinion is that the whole mechanism of anti-sperm antibodies is still not known. It is always important to remember that many men, without having a vasectomy reversal, have anti-sperm antibodies caused by testicular trauma, cycling and previous groin surgery and still manage to father children.

After a vasectomy reversal, couples can choose to have a semen analysis done after three months, in which a sample is taken in our WHO accredited semen analysis suite to analyse the sperm’s motility and anti-sperm antibodies, and establish the likelihood of falling pregnant.

The Vasectomy Reversal Centre

In his extensive experience at The Vasectomy Reversal Centre in Nottingham, Mr Harriss has seen many patients have pregnancies after vasectomy reversal. You’ll be pleased to hear that vasectomy reversals can be so effective that some couples don’t make it to the three month semen analysis, having already conceived!
